Description
Technical Field
The invention relates to a body temperature monitoring device, in particular to a non-contact animal body temperature monitoring device.
Background
The body temperature change of the animal is closely related to the growth condition of the animal, and the monitoring of the body temperature change of the animal can accurately judge the stages of estrus and the like of the animal, so that targeted treatment is carried out, and the breeding benefit is improved. Meanwhile, in animal husbandry, the whole density of animals is high, and large-area infection is easily caused if diseases can be transmitted. The conventional manual measurement mode has low efficiency and is not easy to operate.
A certain difference value exists between the body surface temperature of the animal and the actual body temperature, the difference value is related to the environmental temperature, and the body temperature cannot be accurately reduced only by judging the body surface temperature.
The conventional body surface temperature measurement technology is greatly influenced by animal hair and is specific to livestock such as cattle, sheep and the like. The body surface temperature cannot be accurately measured due to the presence of hair.
At present, the following technologies are mainly used for measuring the body temperature of an animal:
1. an external conduction temperature measurement method. Through wearing at the animal body surface, temperature-sensing device and animal hair use the bandage laminating, under the ideal condition, temperature-sensing device can tend to unanimous with animal body temperature. The temperature of the body surface of the animal is monitored by monitoring the temperature of the thermal sensing device. The main problem of the technology is that the animal hair has better heat insulation effect and larger attenuation. Meanwhile, the real-time performance of heat conduction is poor, and when the temperatures of the two parts are close to each other, a long time is needed for temperature synchronization.
An in vitro infrared temperature measurement method. The device is also worn on the body surface of an animal, adopts a technical scheme similar to a human body temperature measuring gun, uses an infrared thermopile sensor, and is additionally provided with a Fresnel lens to realize non-contact measurement of the target temperature. The scheme also has larger influence on the surface hair heat insulation of the receptor, and has larger difference between the infrared emissivity of the hair and the skin, thereby further increasing the error of measurement. Meanwhile, because the original accuracy of the thermopile is low, a long-time oversampling technology is required to improve the accuracy. It normally takes one second to acquire accurate data. The wearable animal equipment requires that the system has extremely low power consumption and meets the requirement of long-term work of battery power supply. An excessively long sampling time will reduce the usage time of the system.
An in vivo temperature measurement method. The ultrahigh frequency rfid temperature measurement tag is used as a representative, the temperature measurement tag can be implanted under the skin or in the body of an animal, the body temperature of the animal is regularly obtained through reading equipment, and the temperature measurement accuracy is high because the temperature measurement tag is directly implanted in the animal body. The defect is that the acquisition needs to be close to acquisition equipment, and long-term online monitoring cannot be realized. And the whole implementation difficulty is higher, which is not beneficial to popularization.
In conclusion, the technical effects are not good, and therefore, the non-contact animal body temperature monitoring device is designed.

Drawings
The invention is described in detail below with reference to the drawings and the detailed description;
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the utility model provides a non-contact animal body temperature monitoring devices, including equipment principal 1, infrared sensor 2, far infrared lens 4, elastic telescopic mechanism 5, ambient temperature sensor 7, elasticity bandage 8 and main control unit 9, equipment principal 1 is fixed at animal neck or other positions through elasticity bandage 8, be provided with main control unit 9 in the equipment principal 1 and the infrared sensor 2 that links to each other with main control unit 9, ambient temperature sensor 7, be provided with elastic telescopic mechanism 5 on the equipment principal 1 of infrared sensor 2 front portion, the sealed far infrared lens 4 that is provided with in 5 outer ends of elastic telescopic mechanism, far infrared lens 4 sets up with 6 direct contact of animal skin, elastic telescopic mechanism 5 is deep into inside the animal hair.
The far infrared lens 4 adopts a far infrared dustproof and waterproof optical filter, so that the sealing and the waterproofing of the whole structure are ensured, and meanwhile, the transmission of infrared light is not influenced.
The farthest distance from the sensing point of the infrared sensor 2 to the far infrared lens 4 is 3cm, the FOV of the infrared sensor 2 is 10 degrees, and the diameter of the far infrared lens 4 is 1 cm.
The far infrared lens 4 is a silicon wafer far infrared lens with the transmission wavelength of 5-14 mu m.
The device main body 1 of the embodiment is directly fixed on the neck or other parts of an animal by using a binding band, and the infrared sensor 2 is core temperature measuring equipment and has the advantages of high-speed temperature acquisition, small view field angle and the like; the infrared field 3 indicates an effective infrared temperature measurement range, and the far infrared lens 4 realizes the functions of water resistance, dust resistance and no infrared ray obstruction; the elastic telescopic structure 5 is provided with an elastic multi-joint structure with adjustable length and is used for penetrating into animal hair to reduce measurement errors; the animal skin 6 is in direct contact with the far infrared lens at the top end of the elastic telescopic structure; the environment temperature sensor 7 detects the change of the environment temperature and is used for compensating the real body temperature of the animal; the elastic bandage 8 is used for fixing the equipment to the neck or other parts of the animal; the main controller 9 is a system processing unit and is responsible for sensor data acquisition, temperature compensation, transmission and the like.
The infrared sensor of the present embodiment: the magnitude and wavelength distribution of infrared radiation energy of an object are closely related to the surface temperature of the object. Therefore, the surface temperature of the object can be accurately determined by measuring the infrared radiation of the object, and the infrared temperature measurement utilizes the principle to measure the temperature. The infrared temperature detector consists of an optical system, a photoelectric detector, a signal amplifier, signal processing and outputting parts and the like. The optical system converges the infrared radiant energy of the target in the field of view, and the size of the field of view is determined by the optical parts of the thermometer and the position of the optical parts. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. The signal is converted into the temperature value of the measured target after passing through an amplifier and a signal processing circuit and being corrected according to an algorithm in an instrument and the target emissivity.
The Field of view (FOV) of infrared temperature measurement is equivalent to the range that the eyes of the sensor can see, and the opening sizes of the eyes of different types of sensors are different, so that different temperature measurement capabilities are determined. To accurately measure the temperature of the object, the whole FOV must be "filled" by the measured object, otherwise the external object temperature will be measured, resulting in an erroneous measurement result, and the target Tobj, which has too small an area, cannot completely cover the field angle, resulting in the Terror area entering the sensor field of view, thereby obtaining an erroneous result.
Aiming at the design of the detection device, due to the existence of the telescopic lens, the induction electricity of the infrared lens distance sensor has a certain distance. At this time, the field angle needs to be reduced, or the diameter of the infrared filter needs to be increased, so as to ensure that the FOV field angle of the infrared sensor is not blocked by the whole telescopic lens area.
According to the design, the farthest distance from the sensing point of the infrared sensor to the telescopic lens is 3 cm. An infrared sensor with a FOV of 10 degrees is taken, and according to a trigonometric function, the FOV diameter is 0.525cm at a position of 3 cm. The far infrared filter lens with the diameter of 1cm is selected, so that the requirement that the FOV is not shielded can be met.
In order to realize the overall dustproof and waterproof performance of the equipment and ensure the long-term stability of the infrared sensor, the infrared sensor needs to be prevented from being exposed in the air for a long time. The special far infrared filter is arranged at the top end of the elastic telescopic structure. The temperature of the normal body temperature of the mammal is 8-12 um in wavelength. The silicon chip far infrared lens with the transmission wavelength of 5-14um is selected and used, and the transmittance is more than 80%. Can meet the requirements of the system. Because the infrared light which penetrates through the lens has certain loss, the loss value is compensated by an algorithm in the compensation stage, and the original precision of the sensor can be restored.
The telescopic lens structure is used for realizing close fit with the skin of an animal. Cylindrical elastic telescopic structure cooperation elasticity bandage about the diameter 1cm can make the temperature measurement camera lens go deep into in the animal hair, and the skin is pressed close to more closely, promotes the precision and the efficiency that body temperature gathered.
The ambient temperature and the body surface temperature are closely related, and the lower the ambient temperature is, the lower the body surface temperature is under the condition that the human body temperature is constant. And an ambient temperature sensor is arranged on one side of the device, which is far away from the animal body, so that the real ambient temperature is sensed.
Meanwhile, according to the attenuation curve obtained by the experiment, the attenuation conditions under different environmental temperatures are measured, and a corresponding compensation table is established. The actually measured body surface temperature is corrected by a temperature compensation meter to obtain body temperature data with higher precision.
The working principle of the specific embodiment is as follows: when in use, the main body 1 of the temperature measuring equipment is fixed on the neck of an animal through the elastic bandage 8, so that the temperature measuring equipment is close to the skin of the animal as much as possible; the small-diameter temperature measuring lens consisting of the elastic telescopic structure 5 can enable the lens to be easier to penetrate into animal hair, and the influence of the animal hair on the temperature is reduced; the far infrared lens 4 protects the components inside the equipment, and the waterproof performance of the equipment is realized. The far infrared lens has good penetrability to red light in a body surface temperature range, and can ensure the final measurement precision; the infrared temperature sensor 2 is not changed along with the extension and contraction of the lens, but is fixed at the bottom of the equipment, and finally the surface temperature value of the target is measured by the infrared sensor through the lens with a small view field angle; the main controller 9 collects the body surface temperature of the animal through an infrared temperature sensor and passes the body surface temperature; the environment temperature sensor 7 collects the environment temperature, calculates the real body temperature of the animal by combining the body surface temperature and the environment temperature through a built-in compensation algorithm, and provides data basis for judging the body state of the animal.
The specific implementation mode adopts a compensation algorithm:
the body surface temperature and the environment temperature of the animal are directly collected by the device, the body temperature of the animal is not conventionally considered, and the real body temperature needs to be obtained through conversion of the body surface temperature and the environment temperature.
At present, the table look-up method is common, and different body surface temperatures correspond to different body temperatures. However, the table look-up method has a disadvantage that the table look-up method cannot bring the two-dimensional array data into the environment temperature generally, because the two-dimensional array data of the two variables are too large, the original accurate data are difficult to obtain, but the influence of the environment temperature is not negligible, and the temperature difference between the body surface temperature and the real body temperature is greatly different under different environment temperatures.
And obtaining an approximate function equation among the body surface temperature, the environment temperature and the body temperature through long-time testing and data statistics.
